便携式储罐底板漏磁检测器的研制

A Portable Magnetic Flux Leakage Detector for Tank Floors

针对储罐底板检测过程中大型检测设备不易接近储罐边角、盘管下部等复杂区域的问题,研制了MScan-II便携式储罐底板漏磁检测器。该设备主要由电子主机和扫描器两部分组成。电子主机实现数据处理及人机交互的功能,扫描器则完成底板磁化及磁场信号采集的工作。使用该设备可方便且有效地检测出储罐底板一定深度范围内的腐蚀缺陷。

A portable detector based on magnetic flux leakage is developed to detect the defects in tank floor, especially in the complicated area such as rim of tank and the area under pipes. The new tool consists of the main-machine and the scanner. The scanner is used to magnetize the tar- get floor and to detect magnetic signal. The main-machine is used to achieve data collection and process and to accomplish human-computer interaction. The use of the implement can be conducive to the effective and convenience inspection for defects with a certain extent of deepness in tank floor.
